  • Patent number: 6585602
    Abstract: The invention relates to a plunging assembly for a driveshaft, especially for being used in the driveline of a motor vehicle. The plunging assembly comprises a tubular outer joint part (3) with a longitudinal axis and circumferentially distributed outer running grooves (5) extending parallel to the longitudinal axis; an inner part (1) with inner running grooves (10) extending parallel to the longitudinal axis, as well as a plunging unit (2) with a cage (16) and balls (15) provided for torque transmitting purposes. Furthermore, there are provided means for delimiting the path which can be covered by the inner part (1) relative to the outer part (3) during the moving-in and moving-out motion. The means being arranged between the inner part (1) and the plunging unit (2) as well as between the plunging unit (2) and the outer part (3). The length of the inner running grooves (10) differs from that of the outer running grooves (5).
